I agree with most. We went third week Oct. 2004 adn weather was great - even for a cold natured person like me. I wore jeans at night but shorts and t-shirts during the day. Was a little chilly in the AM and PM for water rides so I rode them at mid day (again, I am always cold). Not all WDW pools are heated. we visited a friend at Contemporary and it was not heated. My daughter swam in it and the ASMusic heated pool.
great weather, no crowds. LOVED IT! Gone the last two Octobers with great success. If you do the Halloween stuff and skip the trick or treating and ride, ride, ride. Of course the little ones like the trick or treat but luckily my DD has outgrown that.
